a boy mass increases by 12% between is 10 and 11birthday it is mass was 52 kg on his 10 birthday whats was the amount on his mass on his 11 birthday
12 % = 12 / 100
52 * 12 / 100 = 624 / 100 = 6.24
52 + 6.24 = 58.24 kg
OR
100 % + 12 % = 112 % = 112 / 100 = 1.12
1.12 * 52 = 58.24 kg
To calculate the amount of mass the boy gained between his 10th and 11th birthday, we need to determine the increase of 12% of his mass on his 10th birthday.
Step 1: Calculate the increase in mass:
Mass increase = 12% of 52 kg
To find the 12% of 52 kg:
Mass increase = (12/100) * 52 kg
Mass increase = 0.12 * 52 kg
Mass increase = 6.24 kg
Step 2: Calculate the mass on his 11th birthday:
Mass on 11th birthday = Mass on 10th birthday + Mass increase
Mass on 11th birthday = 52 kg + 6.24 kg
Mass on 11th birthday = 58.24 kg
Therefore, the amount of mass on his 11th birthday is 58.24 kg.
To find the amount of mass on the boy's 11th birthday, we need to calculate a 12% increase from his 10th birthday's mass.
Step 1: Determine the 12% increase of his 10th birthday mass:
12% of 52 kg = (12/100) * 52 kg = 6.24 kg
Step 2: Add the increase to his 10th birthday mass to find his 11th birthday mass:
52 kg + 6.24 kg = 58.24 kg
Therefore, the boy's mass on his 11th birthday would be 58.24 kg.
